Description

Lars / Lena and Leon are Nixie clock kits all based on the same mainboard and only differ by the enclosure and the Nixie tube types.

During this development, many wishes of customers and the experiences of the previous clock "Manuela" were taken into account, for example the dual board design with interchangeable tube board for compatibility between the tube types. However, because of the small size of the clock, it was necessary to use SMT assembly. These tiny parts are already assembled and soldered.
Also the latest converter technology with voltage multiplyer was introduced with maximized efficiency and thus low self-heating. Therefore it was possible to power the clock via USB even with its high Anode voltage.
A jack for external time signal receiver and an internal slot for the ASK module are also implemented as a dedicated DST button for fast switching between summer and winter time.
Furthermore the high functionality of the clock in addition with alarm function, night mode, shutdown on weekends or weekdays and the selectable RGB tube lighting will convince you.

You will get the complete kit with all the necessary electrical and mechanical parts, even the enclosure and the Nixie tubes, to build this piece of jewelery in a smooth evening as shown in the pictures.

USB power supply and time signal receiver are available as options.

Features

  • Hours, Minutes and Seconds display
  • 3 x 2 multiplex for less tube noise and higher brightness; based on the modern Supertex HV driver HV5812
  • Selectable 12 or 24 hour display modes
  • Uses a Quartz Crystal Oscillator as timebase with software adjustable accuracy
  • Programmable leading zero blanking
  • Date display in either DD.MM.YY or MM.DD.YY or YY.MM.DD format
  • Programmable date display each minute or selectable with a single button push
  • Programmable "shift in / out" optical effect for date display
  • Alarm with programmable snooze period
  • Dedicated DST button for easy switching between DST and standard time
  • Super Capacitor backup keeps time during power outages for some hours
  • Simple time setting using two buttons
  • Five programmable column settings: (Flashing AM/PM indication, illuminated AM/PM indication, always flashing, always on / off)
  • Seconds can be reset to zero to precisely set the time
  • Programmable night mode - blanked or dimmed display to save tubes life or prevent sleep disturbance
  • During night mode briefly pushing a button turns on the display for programable time span
  • Indicator LEDs dim at night mode too to prevent sleep disturbance
  • Weekday aware „Master Blank“ function to turn off all displays on weekends or working hours
  • Separate modes for column tubes during night mode
  • Standard or fading display modes as an eye-catcher
  • Standard digit change, fading digits or fading with Scrollback effect
  • „Slot Machine“ effect to prevent cathode poisoning, programable time, disabled during night mode
  • RGB controller with 729 different possible colours for the LED tubes lighting. Have a different colour of your choice every hour or autochanging colours with variable speed
  • All user preferences stored in non-volatile memory
  • Anodized aluminium frames from Fischerelektronik in Luedenscheid / Germany
  • Lars incl. 6 x IN-17 russian Nixie tubes (9 mm digit size)
  • Lena incl. 4 x IN-12 and 2 x IN-17 russian Nixie tubes (18 and 9 mm digit size)
  • Leon incl. 6 x ST-12C Nixie tubes from Bharat Electronics Ltd (15 mm digit size), clock with glas stand from König & Meyer on request
You will need
  • 3 hours of your evening time with no hurry
  • A clear, well-lit area in which to work
  • Electronic iron and fine electronic solder
  • Multimeter to check the generated voltages
  • Electronic tools
  • A loupe may be helpful
  • TX10 (Torx) Allen screwdriver
  • Enjoyment of your work of course
  • Download of the assembly manual
  • USB power supply 500 mA (offered separately)

RFT receivers

NTP receiver
The modern art of time keeping:
Via Internet and a domestic Wi-Fi the time data will be received from a "timeserver-pool", converted into a pseudo GPS format and interpreted by the clock.
  • Easy placement
  • The NTP must be able to connect to a 2,4 GHz Wi-Fi network
  • Only onetime configuration through Laptop / Tab or Mobile Phone with the web browser
  • No software or App installation necessary
  • World time (UTC) is transmitted, which means that the clocks have to be configured once for the corresponding time zone and need to be set between DST and Non-DST twice a year by pressing a button
  • Can be used worldwide

DCF receiver
The proven time keeping method in Germany and neighboring European countries:
From radio station "DCF-77" in Frankfurt/Main, the time signal is continuously transmitted and received within a radius of about 1,000 km. The external DCF receiver forwards the signal to the clock for synchronization.
  • Orientation to the radio station in Mainflingen near Frankfurt is necessary
  • Unfortunately interference-prone 77.5 kHz long-wave transmission, therefore reliable synchronization only at night hours
  • During synchronization the Nixie tubes should be switched off (can be set-up in the options menu of the clocks)
  • Central European Time (CET) is transmitted with automatic switching between DST and Non-DST
  • Can be used in Germany and the neighboring European countries

Wireless GPS
The wireless way of time keeping, specially with multiple clocks:
The data sent by the GPS satellite system is received (similar to the car's navigation system) and converted into a 433 MHz signal, then transmitted intermittently and received from an internal fitted ASK module.
  • Placement the Wireless transmitter on a window frame with a clear view to the horizont is required
  • Wall outlet for powering the Wireless transmitter necessary
  • 433 MHz signal strenght up to 20 m indoor
  • Every clock must be equipped with an internal ASK module
  • One Wireless transmitter can be received by any number of clocks
  • World time (UTC) is transmitted, which means that the clocks have to be configured once for the corresponding time zone and need to be set between DST and Non-DST twice a year by pressing a button
  • Can be used worldwide, but specially intended for Export, therefore the manual is only available in english speech
These wireless components consist of the following devices
1.: A wireless GPS receiver with USB power supply for placement on a window frame.
2.: An ASK module for fitting into the clock.

If you want to use Wireless GPS synchronization for the first time, we recommend to order a Wireless Set 3 as all necessary components are already included. Later, to expand to every new clock, you only need an internal ASK module.
